To all' whom it 'may concern:

VBe it known that I, FREDERICK H. TIDNAM, a citizen of the United States, residing at Oklahoma city, in the countyof Oklahoma and Territory of Oklahoma.,

haveinvented certain new and useful Improvements in-'Telegraph-Poles, bf which the following is a specification, reference being had therein to the accompanying drawing, Y

This invention relates to an improvement in telegraph poles, and particularly to a cement pole or post. The object of the invention is the construction of a pole or post, having a cement bod-y, and said body rcinforced and strengthened by a peculiarly-constructed, metallic framework.

Another object of the invention is the construction of a composite or compound pole, comprising, preferiarly-constructed, metallic framework or cage` f With these and other objects in view, the invention consists of certain novel constructions, combinations, and arrangementsof parts, as will be hereinafter fully In the drawings: Figure l is a vertical, central, sectional view of a pole constructed in accordance with the present intention. Fig. 2 is a horizontal, sectional view'takeln on line 2, 2, Fig. l, looking in the direction of the arrow. Fig. 3 is a vertical, central, sectional View of the metallic framework or cage, which is embedded in the cement of a finished post, Fig, 4 is a horizontal, sectional view taken on line 4, 4, Fig. 3, looking in the direction ofthe arrow. Fig. 5 is an enlarged View of one of the clamps of the framework, which secures a single longitudinally-extending wire or rod and ahorizon tal wire or rod together. Fig. 6 is another embodiment of the present invention, showing a two-way clamp for fastening two crossing wires or rods together. Fig. 7 is a vertical, sectional vieulr pole. Fig. 8 is a transverse, sectional view of the core, showing the wedge therein for holding the sections inV an expanded position. y

Referring to the-drawings by numerals, l designates the body of the plastic orvcement pole or post, which is formed by placing the material in a green state in any suitable mold or receptacle. Prior to the placing of the cement or plastic material in the mold or-receptacle, I, preferably, place the sectional core shown in Figs. 7 and 8 therein, for producing a hollow center 2 The core comprises semi-cylindrical tapering sections 3, 3, which sections constitute a substantially conical structure. The sections overlap at their lona wedgeor filling means 4, these sections 3 can be expanded and held in their expanded or adjusted position until the cement body'l has become hardened.

To prevent the sections 3 from being expanded too far, I, preferably, wrap an ordinary string or cord producing a desired diameter.

It is to be noted that by means of the tapering'or conical structure of the core, the poleI is formed with a similarly-constructed, hollow portion y2, and, furthermorc, this hollow formation of the pole not only greatly reduces itsweigh`t, but the sides of the body l. are of the same thickness throughout their length, so that the framework, Fig. 3, is surrounded at all portions with substantially the same amount of cement, whereby a very durable structure is produced. Furthermore, by means of the pointed end 5 of the sectional cover, an integral cap 6 is formed upon the body l, which cap is conical-shaped, andof a uniform thickness. It is to be notedA that the inner end of the hollow portion 2 is formed with a conical portion 7, while its opposite lower end 8 is open.

The framework orcage for the pole or post comprises longitudinally-cxtending wires or rods 8, and

horizontal, annular wires or rods 9. In the following v 'member 8 and auxiliary member 9, the-two members are securely fastened together, by means of a clamp l0, see particularly Fig. 5. This clamp .l0 comprises a horizontal body portion l1, anda vertical, body portion l2. Illitegral with the horizontal body portion 1l and the vertical' body portion 12, are lugs 1S, which are bent, preferably, around the auxiliary member 9, constituting an annular structure. The body portion l2 of the clamp is outwardly bulged, as at 14, Figs, 2

and 4, constituting a way or groove, in which fits the A primary member 8. By means of the annular' lugs 13 and the grooved structure of the body portion '1 2, the .two members are securely locked together by the clamp. Furthermore, while the clamp does not weaken the cement body of the pole, still by reason of the body portions l1 and l2 of the clamp, it will be seen that the wholel structure of the pole will be strengthened, as the metallic body portion at the crossing point of cach two of the primary and auxiliary members is widened or thickened. In other words, the peculiarly-constructed clamp constitutes amenlarged or broadened portion of the primary and'auxiliary wires at their crossing point.

In Fig. 6, I have shown another embodiment of the present invention, comprising a two-way clamp 10, through which extends a vertical, primary member 8,

`rand a horizontal, auxiliary member 9;k This clamp 10 can be fixedly fastened to the members by any suitable means, and as is the case With clamp l0, the

"members at their crossing or junction point will be greatly increased in strength,v besides fastened to gether, so that the uniform shape oi the framework will be retained by the clamps until the cement vor plastic material hardens. It will be notedthat I have provided clamping and fastening means at the crossing point of each two primary and auxiliary members, and said clamping and fastening means extending parallel with said members and greatly reinforcing the. same. i

The ends of the longitudinally-extending members S are, preferably, bent over, in the form of hooks l5, Fig. 3, against thi` outer edges and sides of the clamps.

By means or' the hooked ends l5 of the primary members 8, all liability oi the clamps movingT too far outward, prior to their being xedly secured to the wires, is obviated. Furthermore, the hooks l5 slightly increase the size of the framework contiguous to the ends oi the pole, which also increases the strength oi the iinished article.

What I claim is:

1. A cement telegraph pole, comprising a body having a conical-shape, hollow, central portion` producing sides of the body of the same -thickness throughout their lengths, said body provided with an integral, conical cap of uniform thickness, a metallic framework embedded in said body, said framework comprising a plurality of longitudinallyextendng primary members, horizontal, annular, auxiliary members engaging said primary members, and clamps connecting each two primary and auxiliary mem,- bers at their crossing point, saidclamps comprising horizontal and vertical body portions, the vertical body portion outwardly bulged, said outwardly-bulged portion constituting a groove, the primary member positioned in said groove, and said horizontal body portion provided with annular lugs surrounding the auxilliary member.
